International Classification:

A01K 6304

US Classification:

119259

Abstract:

A device for cleaning gravel in an aquarium includes a pump connected to a gravel casing such that the pump forms the top of the structure and the gravel casing the remaining body below the pump. The gravel casing houses the pump intake section and filtering material and when its base is placed over an area of gravel during cleaning will draw a debris and impurities water mixture from the gravel, and into the filtering material where the debris is trapped, thus filtering the water mixture which is returned to the tank via the pump's discharge section.

International Classification:

A01K 6304

US Classification:

119259

Abstract:

The present invention is directed toward removing debris and impurities from the surface of aquarium gravel. The method comprises the utilization of a gravel casing, a pump and a filter, all interconnected. When the casing is held firmly against the floor the aquarium during operation, water enters into the casing by way of one or more apertures on the casing's wall. Gravel within the casing is thus churned with such velocity as to promote distinct patterns of water and gravel rotational motion which when sustained act upon the surface of the gravel particle.
